There are many cases where the use of security roles can make it difficult or even prevent fraud. The classic case is that of paper money or paper used in identification documents.
As security paper is usually meant a paper having one or more security features that make it difficult to falsify and / or copy the original.
By using a security paper it is possible to produce difficult or even virtually impossible documents to be produced outside of their original scope of production or reproduced / copied without significant physical or aesthetic differences. It is therefore not possible to produce "originals" and / or copies or reproductions with the same characteristics as authentic originals.
There are several types of papers that incorporate one or more security features. The main features that may be present in a security role are as follows:
Water mark
Watermarks, or watermarks, reproduce a design or text on paper thanks to variations in fiber density on paper. The subject can be seen in transparency but does not appear when the paper is in normal light. There are two types of filigrees, those made in "Flat Table", which are simpler and have less detailed, and those made in "Round Shape" that are more sophisticated, have superior detailing and can have perspective and three-dimensionality. Reproduction of this physical feature of the paper is very difficult
Iridescent platelets
These are minidiscs randomly spread across the paper surface or arranged in bands that change color depending on the angle of light. This light gives the platelets a shiny appearance that is not reproducible by photocopy or scanner.
Fibers or confetti
The fibers are short synthetic yarns and confetti small disks, visible or invisible to the naked eye, incorporated into the mass of the paper and spread throughout the surface or in bands. They feature a wide variety of colors, shapes and lengths. There are usually three versions:
- visible to the naked eye, but not sensitive to ultraviolet light.
- visible to the naked eye and also sensitive to ultraviolet light, emitting brightness or changing color when under this type of illumination.
- invisible to the naked eye, appearing only under ultraviolet illumination.
Anti-copy systems (hidden text)
These are virtually invisible prints on the original paper background (usually with the "copy" or company / document issuer mark), which appear clearly when trying to reproduce the document through both a color and b & w copier , thus making it clear that it is a copy and not an original, and that the copy may have been made without authorization.
Hilites
They are tiny particles, visible or invisible to the naked eye, fluorescent under ultraviolet light. Its fluorescent effect is difficult to reproduce by printing.
Iridescent coating
The iridescent coating is a motif deposited on the surface of the paper and whose color changes depending on the angle of light. It can be deposited in strips or scattered with custom motifs. The iridescent effect and the glossy appearance are not reproducible by photocopying or scanner.
Safety wire
The security threads are embedded in the paper in the mass, or windowed and can be personalized by a mini or microprinting, a withdrawal of metallization, a fluorescence of the wire or the text, or a holographic effect. They are very difficult to reproduce and have an excellent level of security.
Holographic track
It is a hologram (usually custom) deposited in strip on paper. The visual effect of light diffraction can not be reproduced by scanner or by photocopying.
Holographic label and mark
Label, adhesive or not, or mark presenting on all its surface or only part, a customized or standard holographic image. It can be without partial or total metallized configuration (greater protection), colored, destructible etc ...
Invisible images
These are images or writings invisible under normal light but appear when illuminated with ultraviolet light. Allows validation of original documents. It is a difficult technology to reproduce.
Adhesive film
Polyester coated with an adhesive inhibitor and covered with an acrylic emulsion. When the film is detached, a message is transferred to the media, marking it permanently.
Instant check treatment
This is a special paper treatment that makes it sensitive to a specific type of colorless ink. This treatment allows the authentication of the document, because when the ink (usually a special pen) comes into contact with the paper a chemical reaction makes the ink black, instantly.
Special impressions and inks
These are special inks that are used to produce safety papers with the following characteristics:
- Scraping paints (prevention of mechanical action).
- Irreversible thermochromic inks (thermal contrast).
- Invisible paints (zero background, chemical reaction).
- Transparent inks (based on oils, simulates watermarks).
Chemical reactions
Chemicals are incorporated in the paper to react to the attempts of chemical fraudsters of the fraudsters. In case of falsification, these reactions are concretized by the appearance of colored spots, varying according to the products.
Synthetic paper
Made from a special coated polyethylene film, it is resistant to water, grease, chemicals, temperature variations and tear. Suitable, therefore, for several applications whose conditions of use are demanding and can be used as easily as paper.
Bookmark and Share
They can be Binary, Analog, Organic, DNA or RFID. They allow the identification of the products (or their components) from manufacture to sale to the final consumer, through the use of sophisticated reading and control systems.
Most common applications
Security roles can or could be used for multiple critical applications, such as:
Contracts, confidential documents, certificates of authenticity, identification documents, official documents (notaries, certificates, licenses ...), diplomas, medical records, checks, authorizations, invoices, tracing or authenticity labels, tickets / tickets etc. ..
